Rushing to work

Rushing to work, I was driving too fast and as a result was pulled over by the highway patrol. The state trooper noticed that my shirt had the name of a local high school on it.

- I teach math there, I explained.

The trooper smiled, and said,

- Okay, here's a problem. A teacher is speeding down the highway at 16 m.p.h. over the limit. At $12 for every mile, plus $40 court costs, plus the rise in her insurance, what's her total cost?

I replied:

- Taking that total, subtracting the low salary I receive, multiplying by the number of kids who hate math, then adding to that the fact that none of us would be anywhere without teachers, I'd say zero.
